Primary Research on Salt Tolerance of Jerusalem artichoke
摘要
Abstract
In order to study the salt tolerance of Jerusalem artichoke, the growth and physiological Indexes of J.artichoke were measured at different salt stress (ECe 0,10,20,30,40,50,60 dS/m).The results showed that:Under ECe=0-30 dS/m,J.artichoke could germinate and normally grow, and could not survive under ECe≥40 dS/m, with the treatment time prolonging, the seedling height and fresh weight, qP and NPQ reduced obviously at ECe≥ 20 dS/m (P ＜ 0.05), and there are no obviously changes at ECe= 10dS/m (P＞0.05);The changes of water contents of roots and shoots had no differences compared with control(P＞0.05),and the water contents,Fv/Fm and chlorophyll of leaves increased first at ECe= 10 dS/m and then decreased at ECe≥20 dS/m and reached the lowest at ECe=30dS/m.So,the seedling height, fresh weight, the water contents of leaf, Fv/Fm, qP, NPQ and chlorophyll content could be used as important indicators to evaluate salt tolerance of J.artichoke,and the water contents of root and shoot,dry weight biomass only could be used as reference indexs.关键词
